Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a dispenser capable of reducing the necessity of cleaning, suppressing satellite formation and atomization, and preventing liquid from leaking through a liquid dispensing outlet.SOLUTION: The dispenser 10 for applying a small amount of liquid to a substrate includes a dispenser body 12, an actuator 10b within the dispenser body, and a dispensing element 50 including a dispensing element body 52 removably coupled to the dispenser body. A valve stem 60 is attached so as to reciprocate within the dispensing element body. Additional aspects include a deformable valve seat, a deformable and resilient valve stem tip, and a method for applying liquid in discrete amounts to a substrate.
